                       AGREEMENT RE ENVIRONMENTAL MATTERS


      THIS AGREEMENT RE ENVIRONMENTAL MATTERS ("AGREEMENT") is dated June 18,
2004 for reference purposes and entered into by and between 301 INDUSTRIAL LLC
("301"), a limited liability company organized and existing under the laws of
the State of California, with its principal office at 3629 Grand Avenue,
Oakland, California 94610; between 301 HOLDING LLC ("301 HOLDING"), a limited
liability company organized and existing under the laws of the State of
California, with its principal office at 3629 Grand Avenue, Oakland, California
94610, COMMUNICATIONS & POWER INDUSTRIES, INC. ("CPI"), a corporation organized
and existing under the laws of the State of Delaware, with its principal office
at 811 Hansen Way, Palo Alto, California 94303, as successor in interest by
merger to Communications & Power Industries Holding Corporation; VARIAN MEDICAL
SYSTEMS, INC. ("VARIAN"), a corporation organized and existing under the laws of
the State of Delaware, with its principal office at 3100 Hansen Way, Palo Alto,
California 94304; and PALO ALTO MEDICAL FOUNDATION ("PAMF"), a non-profit public
benefit corporation organized and existing under the laws of the State of
California, with its principal office at 795 El Camino Road, Palo Alto,
California 94301. 301, 301 Holding, PAMF, CPI, and Varian may be referred to
herein collectively as the "PARTIES" and individually as a "PARTY".

      WHEREAS, PAMF and CPI previously entered into an Agreement of Purchase and
Sale dated February 7, 2003, as amended ("PURCHASE AGREEMENT"), whereby PAMF
would acquire the real property located at 301 Industrial Road, San Carlos,
California (the "PROPERTY") on the terms and conditions therein with the
intention to develop a new hospital and medical facilities on the Property. The
Property is currently owned by CPI and was formerly owned by Varian. The
Property has been operated for at least 40 years as a manufacturing facility.
Over time, soil and groundwater at the Property have become contaminated by
various chemical compounds. CPI and Varian have previously entered into
agreements addressing their respective ongoing obligations to each other
relating to the Property. After discussion among the Parties, the Parties have
decided that in order to facilitate PAMF's redevelopment plans and address CPI's
and Varian's concerns related thereto, the Parties will enter into this
Agreement to establish their respective rights and responsibilities with regard
to environmental matters relating to the Property.

      WHEREAS, to facilitate PAMF's proposed construction and operation of a
hospital and medical facilities on the Property, 301 Holding has formed and will
maintain 301 as a single asset special purpose limited liability company wholly
owned by 301 Holding, to take title to and conduct the necessary investigation
and remediation of the Property under regulatory oversight of the Regional Water
Quality Control Board for the San Francisco Bay Region (the "RWQCB") to agreed
upon standards for unrestricted use and to obtain an insurance policy negotiated
jointly by the Parties to insure against the risks associated with the
environmental condition of the Property and 301 Holding will guarantee the
performance of 301 under this Agreement.

      NOW, THEREFORE, in consideration of the foregoing and the mutual
obligations herein contained, the receipt and sufficiency of which are hereby
acknowledged, and intending to be legally bound, the Parties agree as follows:


                                       1

      C.    RWQCB Approvals.

            1. No Further Action Letter. Within five (5) business days after the
Effective Date of this Agreement, commence, and thereafter pursue diligently,
negotiations with the RWQCB and use commercially reasonable best efforts to (1)
obtain the RWQCB's timely approval of the Remedial Action Plan dated June 16,
2004 prepared by Northgate and previously approved by the Parties ("RAP") and
attached as Appendix III C-1, which includes the closure of existing monitoring
wells located on the Property; (2) enter into and perform a prospective
purchaser agreement with the RWQCB on the terms set forth in the form of
prospective purchaser agreement attached as Appendix III C-2, as may be modified
with the agreement (not to be unreasonably withheld) of all Parties ("FINALLY
APPROVED PPA"); and (3) following completion of the "FINALLY APPROVED RAP" (as
defined in Section III.O) pursuant to the finally approved PPA, obtain a written
acknowledgement from the RWQCB that no further environmental response actions,
including institutional controls (including deed restrictions) and/or
engineering controls, is necessary on the Property to allow for "Unrestricted
Uses" of the Property ("NO FURTHER ACTION Letter"). "UNRESTRICTED USES" in this
Agreement shall mean and include residential housing, children facilities (e.g.,
daycare, K-12 schools, preschools, playgrounds), elderly facilities (e.g.,
nursing homes; hospices; convalescent homes; senior centers; assisted living
facilities), places of worship, hotels, motels, hospitals, skilled nursing
facilities, medical facilities, and similar sensitive receptors. For all
purposes under this Agreement, "Unrestricted Uses" shall exclude commercial,
manufacturing, industrial, retail and office uses. The RAP is predicated upon
the requirement and agreement among the Parties that the environmental response
actions defined or provided therein, when performed, will result in remediation
of the Property to a condition that allows the Property to be used for
Unrestricted Uses without the need for institutional controls (including deed
restrictions) and/or engineering controls.

            2. Institutional and Engineering Controls. After 301 completes
performance of the finally approved RAP (including if necessary, as determined
by 301, access to the cost cap coverage portion of the Insurance Policy) and
requests the RWQCB to issue a No Further Action Letter, if the RWQCB indicates
that it will not issue a No Further Action Letter unless 301 implements and
maintains institutional controls (including deed restrictions) and/or
engineering controls at the Property, and if, at that time, 301 has not expended
all funds in the commutation account, 301, in consultation with the RWQCB, shall
undertake such additional environmental response actions at the Property as are
reasonable under the circumstances and as can be implemented without incurring
costs greater than the remaining balance in the commutation account to eliminate
without use of institutional controls (including deed restrictions) and/or
engineering controls, in so far as possible, the environmental conditions that
formed the basis for the RWQCB's refusal to issue a No Further Action Letter.
Upon completion of such additional work, if any, 301 shall request the RWQCB to
issue a No Further Action Letter for its benefit at its cost. If, in response,
the RWQCB indicates that it will not issue a No Further Action Letter unless 301
implements and maintains institutional controls (including deed restrictions)
and/or engineering controls, the Parties will be so informed and have the right
to approve such institutional controls (including deed restrictions) and/or
engineering controls, which approval or disapproval shall not be unreasonably
delayed. If the Parties cannot agree as to such institutional controls
(including deed restrictions) and/or engineering controls, this dispute shall be
submitted to arbitration, in accordance with this Agreement (and the Arbitrator
shall have a technical


                                       3
<PAGE>
advisor approved by the Parties). If a decision is made by the Parties or by the
Arbitrator to implement institutional controls (including deed restrictions)
and/or engineering controls, 301: (i) shall implement and maintain such
institutional controls (including deed restrictions) and/or engineering controls
as are agreed to by the Parties or determined by the Arbitrator, and (ii) shall
record against the Property a permanent deed restriction for the benefit of the
Parties: (x) against the use or development of the Property for Unrestricted
Uses, excluding hospitals, skilled nursing facilities, medical facilities,
motels, and hotels, and/or (y) against the use or development of the Property
for any other uses as established by the RWQCB. If a decision is made by the
Parties or by the Arbitrator to implement additional environmental response
actions at the Property, 301 shall undertake such additional environmental
response actions at the Property and request a No Further Action Letter from the
RWQCB upon completion of such additional environmental response actions. If the
RWQCB indicates that it will not issue a No Further Action Letter unless 301
implements and maintains institutional controls (including deed restrictions)
and/or engineering controls at the Property, then the foregoing provisions of
this Section III C(2) shall again apply and shall be complied with by 301.

      D. Closure of CPI Facility. Monitor CPI's efforts in obtaining regulatory
closure of CPI's facility, including without limitation any regulated waste
management units currently on the Property, as required by the Purchase
Agreement or this Agreement and perform (and cause its RAP contractor and/or its
demolition contractor to perform) the closure responsibilities allocated to 301,
as set forth in Appendix III D.

      E. CPI's Evacuation from the Property. Monitor CPI's evacuation from the
Property, as required by the Purchase Agreement or this Agreement.

      F. Demolition Contractor. Select, hire and pay Pacific States
Environmental Contractors, Inc. (or other qualified contractor(s) and
consultant(s) reasonably acceptable to the Parties and approved by AIG) as the
abatement, demolition and removal contractor(s) and consultant(s) and cause the
abatement, demolition and removal of existing improvements on the Property,
including without limitation abatement of asbestos-containing building materials
and lead paint, in accordance with all applicable federal, California and local
laws and requirements, pursuant to a written contract, a copy of which shall be
submitted to the Parties prior to execution for an opportunity to comment. The
abatement, demolition and removal also shall include equipment which CPI is
permitted to leave on the Property as listed in Appendix V D attached hereto.

      G. RAP Contractor. Select, hire and pay Northgate Environmental
Management, Inc. (or, at 301's option, other qualified contractor and/or
consultant reasonably acceptable to the Parties and approved by AIG) as the
environmental contractor and/or consultant, and cause the remediation of the
Property to be performed in accordance with the finally approved RAP (including
without limitation all environmental response actions required by the finally
approved RAP) and in accordance with all applicable federal, California and
local laws and requirements, pursuant to a written contract, a copy of which
shall be submitted to the Parties prior to execution for an opportunity to
comment.

      H. Other Professionals. Select, hire and pay other professionals
reasonably acceptable to the Parties as necessary to meet its obligations under
this Agreement pursuant to a


                                       4
<PAGE>
written contract, a copy of which shall be submitted to the Parties prior to
execution for an opportunity to comment, with the exception of written contracts
for legal services, which contract need not be provided to the Parties. If 301
selects a professional and submits such proposed hiring and contract to the
Parties as provided herein, each Party shall have five (5) business days to
reasonably disapprove such selection and/or provide comments on the contract. If
no disapproval or comments are given by a Party within such time period, such
Party shall be deemed to have accepted such professional.

      I. General Performance Requirements. Cause its agents and contractors to
complete all work in a professional and good and workmanlike manner and to
comply with all applicable federal, California and local laws and requirements
in connection with its performance of its obligations and rights pursuant to
this Agreement.

      J. Performance of Demolition and Remediation. Except as otherwise
expressly provided in this Agreement, cause and pay all costs for the
remediation of the Property (including all necessary environmental response
actions) and the abatement, demolition and removal of improvements, including
without limitation, costs of preparing and obtaining government approvals of and
in accordance with the finally approved RAP and subject to such modifications as
may from time to time be required by such agencies; costs of performing work
required under the finally approved RAP; costs of performing the closure
responsibilities allocated to 301 as set forth in Appendix III D; assume
ownership of and responsibility for monitoring wells that the RWQCB does not
approve for closure pursuant to Section VI B; costs of design, construction, or
installation of any facilities (including any monitoring wells) required under
the finally approved RAP; and prepayments or deposits required to order
materials.

      K. Costs of Enforcement of Insurance Policy. Pay all costs reasonably
incurred in connection with enforcing the Insurance Policy (on behalf of any

behalf of the other (except as provided herein), and the employee and/or
representative of one shall not be deemed the employee or representative of any
other. Nothing in this Agreement shall be deemed to constitute, create, give
effect to or otherwise recognize a joint venture, partnership or formal business
entity of any kind, and the rights and obligations of the Parties shall be
limited to those expressly set forth herein. Nothing in this Agreement shall be
construed to give any Party the right to manage the day-to-day activities or
control another Party's business. No Party shall have any liability or
obligation to another except as expressly provided herein or in any other
agreement signed by the Party to be bound.

      B. Limited Contact with RWQCB. To facilitate 301's ability to perform its

individually or in concert, contact or attempt to influence the actions of the
RWQCB or any other relevant regulatory agency with regard to 301's obligations
hereunder with respect to the Property without the express advance written
approval of 301. Notwithstanding the foregoing, without any liability under the
preceding sentence any Party may contact the RWQCB or any relevant regulatory
agency if reasonably necessary to cause or ensure that the provisions of this
Agreement and the finally approved RAP are fully complied with, but only if, (i)
such Party has given prior written notice to 301 and PAMF of the alleged failure
of 301 to comply with this Agreement, (ii) 301 does not promptly commence the
cure of such failure and diligently prosecute it to completion, (iii) in the
case of such failure to cure, all Parties shall attend a meeting (which
attendance may be by their representatives and/or contractors) within ten (10)
days of notice thereof by such Party, at which meeting PAMF, CPI and Varian
agree that 301 has failed to comply with this Agreement, and (iv) 301
nonetheless does not immediately commence the cure of such failure


                                       12
<PAGE>
and diligently prosecute it to completion. CPI's actions pursuant to Section V
E, Appendix III D and Section V J and Varian's actions pursuant to Section VI B
shall not be deemed breaches of this provision.

      C. No Transfer of Rights Under Varian Agreements. PAMF, 301 and 301
Holding each represents and warrants to Varian that, except as provided herein,
neither CPI nor any other person has ever, by operation of law or otherwise,
transferred or purported to transfer to it, or conveyed or purported to convey
to it, any right or interest in or to, any of CPI's or any other person's rights
under any of the Varian Stock Sale Agreement and Varian Site Access Agreement
and two Special Release and Settlement Agreements dated September 30, 1996 and

covenants with Varian that, except as provided herein, it will never accept any
such transfer, purported transfer, conveyance or purported conveyance.

avoid disclosure of all confidential information ("INFORMATION") disclosed by
another Party in connection with this Agreement, except for disclosure to the
receiving Party's directors, employees, agents, attorneys, insurers, lenders and
any contractors directly involved with the receiving Party's use of such
Information and as otherwise required, or reasonably deemed advisable, under
applicable law or regulation or as may be required to enforce this Agreement or

may (i) inform any party seeking any environmental response action or
asserting any claim regarding the subject matter of this Agreement, of the
existence of this Agreement and the Party responsible for such  environmental
response action or claim and (ii) contact any oversight regulatory agency (a)
if 301 (or any successor or assign) is not performing its obligations in this
Agreement or is failing to implement the finally approved RAP, as modified or

obligations under this Agreement.

XI.     INJUNCTIVE RELIEF AND SPECIFIC PERFORMANCE

      The Parties agree that money damages alone may be an inadequate remedy for
a breach or threatened breach of this Agreement and that such breach may cause
irreparable injury. Accordingly, the Parties agree that in addition to the
remedies otherwise available, each Party will be entitled to equitable relief,
including injunction and specific performance, as a remedy for any such breach

prior notice to the other Parties, to an entity which succeeds to the Property,
or which acquires more than 50% of the business and assets of a Party. Any
assignment shall not relieve the assignor Party of its obligations under this
Agreement. Notwithstanding the foregoing, PAMF may succeed to the rights of 301
hereunder provided that PAMF assumes the obligations of 301 hereunder, whereupon
301 shall be released from its obligations to be performed from and after the
date of such assumption by PAMF. This Agreement shall be binding upon and inure
to the benefit of the successors and permitted assigns of the Parties.

(including personal injury, death and property damage) arising from, Hazardous
Materials located on or beneath the Property if such alleged exposure occurred,

the Property to 301; or (b) arising out of or relating to claims by third
parties relating to the migration from the Property of any Hazardous Materials

using reasonably applicable professional practices at the time in the San

such party applying customary professional standards or (c) as to CPI only,
arising out of New Contamination.

      B. By CPI and Varian. CPI and Varian hereby release 301, 301 Holding and
PAMF and their respective members, employees, contractors, representatives,
successors and assigns and their respective parents, subsidiaries, members,
directors, officers, employees, shareholders, representatives and agents, from
any and all claims, known or unknown, including without limitation claims for

<PAGE>
      C. By PAMF, Varian and CPI. PAMF, Varian and CPI hereby release 301 and
301 Holding and their respective members, employees, contractors,
representatives, successors and assigns and their respective parents,
subsidiaries, members, directors, officers, employees, shareholders,
representatives and agents, from any and all claims, known or unknown, including
without limitation claims for death, bodily injury, property damage, cleanup
costs and business interruption, arising out of the failure of the RWQCB to
approve or grant the RAP, PPA or No Further Action Letter as desired by the
Parties or AIG's action or inaction, provided that 301 has exercised its
commercially reasonable best efforts to obtain such results as set forth in ,
and has otherwise complied with its obligations under, this Agreement.

      D. Waiver of Section 1542. Each Party acknowledges that it has read and is
familiar with the provisions of California Civil Code Section 1542, which
provides:

      "A general release does not extend to claims which the creditor does not
      know or expect to exist in his favor at the time of executing the release,
      which if known by him must have materially affected his settlement with
      the debtor."

Each Party hereby WAIVES the benefit of the provisions of Section 1542, and of
any statute, principle of common law or case law which would limit the scope of
the releases and waivers contained in this Section XV.

      E. Limitation of Releases. Nothing herein shall be deemed to be a release
by any Party of any other Party of any claim for a breach of this Agreement,
fraud or intentional misrepresentation.

XVI.    GOVERNING LAW

      This Agreement will be interpreted and the rights of the Parties construed
in accordance with California law, and any litigation concerning this Agreement
shall be limited and confined exclusively to the appropriate State or Federal
court located within California.

XVII.   ARBITRATION

      A.    Dispute.  Any dispute, controversy or claim arising out of or
relating to this Agreement, including any dispute relating to interpretation
of or performance under this Agreement ("DISPUTE"), shall be resolved in the
manner set forth in this Section XVII, which shall be in lieu of litigation
in any court (except as provided in Section XVII C regarding provisional
remedies), and the Parties specifically waive any right to a jury trial of
any dispute between them.

      B. Notice and Offer. A Party contending that there is a Dispute shall
notify in writing the other Party or Parties who are directly involved
explaining the nature of the Dispute ("DISPUTE NOTICE"). The affected Parties
will attempt in good faith to resolve the Dispute promptly (but no later than 30
days after receipt of the notice of such Dispute) by negotiations between senior
representatives of the Parties who have authority to settle the Dispute (each, a
"REPRESENTATIVE"). Prior to expiration of the 30-day negotiation period, the
Party who has first notified the other Party(ies) of the Dispute shall submit a
written offer to settle the Dispute.


                                       17
<PAGE>
      C. Provisional Relief. At any time after expiration of the 30-day
negotiation period and prior to selection of the Arbitrator, a Party requiring
provisional relief to maintain the status quo, may seek provisional relief in
court. The granting of such provisional relief shall not constitute a waiver of
the parties' obligations to resolve the Dispute by arbitration as described in
Section XVII D and the Arbitrator shall not be deemed deprived of jurisdiction
to award or modify any provisional relief. Once the Arbitrator has been
selected, the Arbitrator shall promptly determine if any existing provisional
relief should remain in effect and may continue, terminate or modify such
provisional relief.

      D. Proceeding. In the event the Representatives have not resolved the
Dispute within the 30-day negotiation period, the Dispute shall be resolved by
binding arbitration before the arbitrator (the "ARBITRATOR") identified below,
in accordance with the following provisions:

            1. The Parties stipulate and agree that any and all necessary
parties may be joined in the arbitration, but the Parties agree to proceed with
arbitration of all Disputes between themselves even if other parties refuse to
participate. The Parties specifically waive any objection to arbitration based
on the failure or refusal of any other party to be joined.

            2. Within 60 days after the expiration of the 30-day negotiation
period, the arbitration shall be initiated by written notice (the "ARBITRATION
NOTICE") of a demand to arbitrate by registered or certified mail sent by one
Party to the other Party or Parties. If an Arbitration Notice is not given
within the 60-day period, then the right to make a claim based on the Dispute
described in the Dispute Notice shall be forever waived. The Arbitration Notice
shall include a plain statement of the Dispute and the relief requested and
shall select to be governed by either AAA (as described below) or JAMS (as
described below). Within 30 days of receipt of the Arbitration Notice, each
responding Party or Parties shall provide its own plain statement of the Dispute
and the bases of any defenses it intends to assert in response to the demand.
The Parties shall equally share the Arbitrator's fee, as fixed and required by
the Arbitrator in order to initiate the arbitration, although the Parties shall
ultimately bear responsibility for such fee as determined by the Arbitrator.

            3. The Parties shall attempt to agree on a retired judge to be the
Arbitrator. If they are unable to agree, the Parties shall simultaneously
exchange the names of three available retired judges and a judge appearing on
both lists shall be selected. If there is no common available Arbitrator and the
Parties still cannot agree on an Arbitrator, the Parties shall submit further
lists until one is selected. If the Parties have not selected the Arbitrator
within 15 days following the responding Party's statement of its position, the
arbitrator shall be selected in accordance with the applicable rules of
arbitration (AAA or JAMS, as the case may be). The Arbitrator so selected shall
be notified immediately and a date for the arbitration shall be set within nine
months after selection of the Arbitrator. The Dispute shall be resolved by
binding arbitration under the American Arbitration Association's ("AAA")
Commercial Arbitration Rules or the arbitration rules of JAMS (whichever is
elected by the party giving the Arbitration Notice) then in effect, as
supplemented by this Section XVII. To the extent this Section XVII is
inconsistent with the applicable arbitration rules, the provisions of this
Section XVII shall control.


                                       18
<PAGE>
            4. The Arbitrator shall schedule a pre-hearing conference to resolve
procedural matters and arrange for the exchange of information.

            5. Prior to the arbitration, the Parties shall be allowed the
following limited discovery: each Party shall be entitled to receive relevant
non-attorney-client privileged documents and to take up to three fact and/or
expert witness depositions in the discretion of the Arbitrator. Any further
discovery shall only be allowed by order of the Arbitrator upon a showing that
it is critical to the presentation of a Party's claims or defenses. All
discovery shall be completed 30 days prior to the arbitration.

            6. The arbitration shall be completed in no more than ten full
consecutive days, if possible. The following is the timetable preferred by the
parties and which the parties agree cannot be varied except by the Arbitrator
upon a showing that it is critical to the presentation of a Party's claims or
defenses. Each Party shall have two days to present its position using
documentary and testimonial evidence. The Party giving the Arbitration Notice
shall present its case first. One day shall be reserved for argument or the
taking of such further evidence as the Arbitrator may require.

            7. The Arbitrator shall have the power to grant all legal and
equitable remedies, including, but not limited to, injunction, specific
performance, reformation, cancellation, accounting and compensatory damages,
except only that lost profits, consequential damages and punitive damages shall
not be awarded. The Arbitrator shall issue a binding decision within 30 days of
the conclusion of the arbitration. The Arbitrator's interpretations of
California law or applicable federal law shall form the basis of the decision.
The Arbitrator's decision shall be conclusive and binding, and it may thereafter
be confirmed as a judgment by the Superior Court of the State of California,
subject only to challenge on the grounds set forth in California Code of Civil
Procedure Section 1286.2. The validity and enforceability of the Arbitrator's
decision is to be determined exclusively by the California courts pursuant to
the provisions of this Section XVII.

            8. The Arbitrator shall award reasonable attorneys' fees and costs,
including the Arbitrator's fees and expert fees, to the "PREVAILING PARTY". For
purposes of this section, the "Prevailing Party" shall be the Party or Parties
which is or are determined by the Arbitrator to be the prevailing Party or
Parties, provided that a Party may not be the Prevailing Party if the net
recovery by such Party is equal to or less than the written offer from the
opposing party made after the negotiations described in Section XVII B, as
determined by the Arbitrator. The Arbitrator shall have exclusive and binding
authority to determine entitlement to attorneys' fees and costs, including
Arbitrator's and experts' fees, under this section.

            9.    The arbitration shall be conducted in Santa Clara County,
California.  Any party may be represented by counsel or other authorized
representative.

            10. The Arbitrator shall be a retired judge of the Federal District
Court or Court of Appeal or the Superior Court, Appellate Court or Supreme Court
of the State of California.

XVIII.  FORCE MAJEURE

      Force Majeure shall mean an act of nature, flood, fire, earthquake,
strike, lockout, war, civil commotion, act of public enemies, blockage or
embargo, or any injunction, law, order, proclamation, regulation, ordinance,
demand or requirement of any government or any subdivision, authority or
representative thereof, or the inability (other than due to lack of financial
resources) to procure or use materials, labor, equipment, transportation or
energy sufficient to execute the services, or any other cause whatsoever,
whether similar or dissimilar to those enumerated above, which are beyond the
reasonable control of such Party (other than due to lack of financial
resources), which the Party affected has used its reasonable best efforts to
avoid, and which prevent, restrict or interfere with the performance by a Party
of its obligations hereunder. The Party effected by Force Majeure shall give
notice to the other Party(ies) promptly in writing and whereupon the affected
Party shall be entitled to extend the time to perform those obligations
hereunder, to the extent of such prevention, restriction or interference,
provided that the affected Party shall use its commercially reasonably efforts
to avoid or remove such cause(s) of non-performance and shall continue
performance whenever such cause(s) is removed. Nothing herein shall relieve any
Party of its obligation of performance.

XIX.    TERMINATION

      If within 120 days of the Effective Date of this Agreement the RWQCB does
not approve the RAP pursuant to Section III C(1)above, any Party may terminate
this Agreement. In the event of such termination, each Party shall thereafter
cease to have any obligation hereunder (other than for its own breach thereof
and other than Section VIII A and the Insurance Policy which will continue in
effect following any termination of this Agreement). Nothing herein shall be
deemed to release PAMF or 301 from its obligations under the Purchase Agreement
(other than pursuant to the release described in Section V B above). Other than
as provided in this Section XIX, this Agreement may not be terminated.

XXI.    WAIVER

      The waiver by any Party of a breach or default under any provision of this
Agreement by another Party shall not be construed as a waiver of any succeeding
breach or default under the same or any other provision, nor shall any delay or
omission on the part of any Party to exercise or avail itself of any right,
power or privilege that it has or may have under this Agreement operate as a
waiver of any right, power or privilege by such Party.

XXII.   SEVERABILITY

      In the event that any one or more of the provisions of this Agreement
should for any reason be held by any court or authority having jurisdiction over
this Agreement or any of the Parties to be invalid, illegal or unenforceable,
such provision or provisions shall be validly reformed to as nearly as possible
to approximate the intent of the Parties and, if such provision or provisions
can not be validly reformed, such provision or provisions shall be divisible and
deleted in such jurisdiction; otherwise, this Agreement shall not be affected so
long as the Parties are still able to realize the principal benefits bargained
for in this Agreement.

XXIII.  BENEFIT OF COUNSEL/ INTERPRETATION

      The Parties each declare that they have had the benefit of advice and
counsel from separate and independent attorneys at law with respect to all

herewith. Similarly, the presence or absence of language in prior drafts of this
document shall not be used to interpret any provision hereof.

XXIV.   HEADINGS

"herein" or a term of


                                       22
<PAGE>
similar import in any provision shall not refer exclusively to such provision or
section, but rather to the entire Agreement.

XXV.    VARIAN STOCK SALE AGREEMENT/VARIAN SITE ACCESS AGREEMENT

CPI or Varian, as between those two Parties, pursuant to the Varian Stock Sale
Agreement or the Varian Site Access Agreement.

subject matter hereof. There are no representations, agreements, arrangements or
understandings, oral or written, relating to the subject matter of this
Agreement, which are not expressed herein or in an agreement or written
instrument which is referenced herein or referenced in any instrument referenced
herein. No waiver, modification or amendment of any provision of this Agreement
shall be valid or effective unless made in writing and signed by a duly
authorized representative of the Party to be bound.

XXVII.  COUNTERPARTS; FACSIMILE SIGNATURES

      This Agreement may be executed in counterparts, each of which shall be
deemed an original, but which together shall constitute a single document.
Signatures and initials transmitted by facsimile shall be binding; provided
